Process of thick wall honing pipe

- Mar 30, 2020-

Thick wall honing pipe is the main body of the hydraulic cylinder, and its inner hole is generally manufactured by precision machining processes such as boring, reaming, rolling or honing, so that the piston and its seals and supports can slide smoothly and reduce wear; the steel pipe must bear Large hydraulic pressure, therefore, should have high strength and rigidity.

Honing is different from internal grinding. The processing is that a honing head is extended into the hole, and then the machine is driven to rotate, reciprocate, and the grinding rod is raised to perform cutting processing. The honing machine is divided into vertical and horizontal types. The vertical type is more suitable for the continuous production of large quantities of short parts, such as cylinder liners, and the horizontal type is more suitable for the production of longer parts. If the cast iron is processed, the production efficiency is several times higher than that of internal grinding. However, the honing efficiency of steel parts is worse than that of cast iron, but it is still much faster than the method of internal grinding, and the accuracy is not a problem.
